We empathize with you: Autism children are a lot of work. Add a sleep disorder or a nightly tantrum and that does not leave you time to rest. Melatonin is a natural medicine that will help your child, and you, sleep.
Melatonin is a natural, over-the-counter drug. It is produced naturally by the pineal gland. It is secreted when a person is exposed to darkness. Under normal circumstances, the strong

est concentrations are between 2-4 a.m.
According to
Science Daily, melatonin is very effective for children with autism. This isn't the only study out there. There have been over a dozen studies of the effects of melatonin on children. It is not addictive, and there have been no adverse side effects reported in any of the studies. A positive side effect is it can act as an antioxidant. One side effect is grogginess in the morning, and if too much is used the child can become depressed.
We started using melatonin out of desperation. After a night of no sleep, our autism child started having severe tantrums. And the tantrums were in the middle of the night. We had maybe two hours of sleep each night for a week. We used very little, it was about 1/16th of 1 mg. It worked, and it gave us the sleep we needed.
The next morning the results were fantastic. After a full night's sleep we saw huge improvements in our child's behavior. We still use melatonin on our child. The dose increased very little. Generally we use about a quarter to a half a 1 mg tablet.
In the past our autism child would not take pills. Melatonin doesn't have any taste, and it is easy to crush.

At first we just put a tiny bit of powder on our finger and put it on his tongue. Later we tried mixing it in his beverage; this failed completely. The best way we found was to crush the pill and put it in desert, like yogurt or applesauce, before bed. That works well.
The trick with using melatonin is to give it to the child 30-60 minutes before you want them to sleep.
Even though it is a natural, melatonin is a medicine. It really only should be used to help a child sleep who normally would not. A doctor should be consulted before using it. (
Should the doctor want a study to look at, two references have been listed below.)
There are few miracle drugs for autism children, but this is one of them. It helped our child sleep and gave him better behavior. But more importantly it helped us sleep. That gave us the energy to help our child--and that only helps us love him more.

We recommend using Nature's Bounty Melatonin 1 mg. It does not contain any gluten or casien. If a doctor asks to see a study, point them to Ivanenko A, Crabtree VM, Tauman R, et al. Melatonin in Children and Adolescents with Insomnia: a Retrospective Study. Clin Pediatr 2003;42:51-8.
As well, this study is helpful. Smits MG, van Stel HF, van der Heijden K, et al. Melatonin Improves Health Status and Sleep in Children with Idiopathic Chronic Sleep-Onset Insomnia: a Randomized Placebo-Controlled Trial. J Am Acad Child Adolesc Psychiatry 2003;42:1286-93.
